Do we know? Do we have any idea?
There seems to be 2 schools of thought.
1. The initial conditions can be almost any value with universes inflating with different laws of physics. This is the multiverse and string theory 10^500 false vacua view.
2. The initial conditions are more restrained and fine tuned. In Hawking's last paper he took the this view and said he didn't like the smorgasbord view of the multiverse.
I tend to agree with Hawking and I think the universe is computational not physical. As M.I.T. Professor Seth Lloyd says the universe is a Quantum Computer.

So I see what we call physical reality like play dough. It's the parts that we use to create computers, planes and cars by using information that has been processed. So at it's core, the universe processes vasts amounts of information. So how restrained or unrestrained are the initial conditions of the universe or do we know or have an idea?

The universe as quantum computer
This article reviews the history of digital computation, and investigates just how far the concept of computation can be taken. In particular, I address the question of whether the universe itself is in fact a giant computer, and if so, just what kind of computer it is. I will show that the universe can be regarded as a giant quantum computer. The quantum computational model of the universe explains a variety of observed phenomena not encompassed by the ordinary laws of physics. In particular, the model shows that the the quantum computational universe automatically gives rise to a mix of randomness and order, and to both simple and complex systems.

Holographic quantum error-correcting codes: Toy models for the bulk/boundary correspondence
We propose a family of exactly solvable toy models for the AdS/CFT correspondence based on a novel construction of quantum error-correcting codes with a tensor network structure. Our building block is a special type of tensor with maximal entanglement along any bipartition, which gives rise to an isometry from the bulk Hilbert space to the boundary Hilbert space. The entire tensor network is an encoder for a quantum error-correcting code, where the bulk and boundary degrees of freedom may be identified as logical and physical degrees of freedom respectively. These models capture key features of entanglement in the AdS/CFT correspondence; in particular, the Ryu-Takayanagi formula and the negativity of tripartite information are obeyed exactly in many cases. That bulk logical operators can be represented on multiple boundary regions mimics the Rindler-wedge reconstruction of boundary operators from bulk operators, realizing explicitly the quantum error-correcting features of AdS/CFT recently proposed by Almheiri

Spacetime manipulation of quantum information around rotating black holes
The X-ray photons emitted by the https://www.sciencedirect.com/topics/physics-and-astronomy/accretion-disks around rotating black holes are polarized and acquire orbital angular momentum, two degrees of freedom that can encode quantum information. Nevertheless, escaping the accretion disk, photons are passing throughout the extreme warped and twisted spacetime near spinning black holes suffering rotations of polarization angle and changes in the orbital angular moment. We conjecture that these changes in the angle of polarization and orbital angular momentum can implement elementary quantum gates and simple quantum circuits. Consequently, when detected by an asymptotic observer, the photons emitted near rotating black holes encode quantum information that can be measured by actual quantum information technology.
